The Kepco HSF series of 50W, 100W, 150W, 350W, 600W and 1200W/1500W hot-swappable plug-in power supplies are designed to be combined in an N+1 fault-tolerant power system. Built-in forced current sharing and or-ing diodes are provided for this purpose. HSF may also be used independently as a multi-output power supply.
Remote on-off control is standard in the 600W and 1200W/1500W models using either an external power source (voltage applied to RC terminals) or by mechanical or logical closure of a contact (without external power source). The 100W-1UR and 150W-1UR models offer remote on-off as an optional feature; contact factory for details.
Power Factor Correction (PFC) - 50W-PFC, 100W-PFC 150W-PFC, 50W-1UR, 100W-1UR, 150W-1UR, 350W, 600W and 1200W/1500W models only.
User configurable
multi-output 3U power rack for up to (3) 350 watt modules, (6) 150 watt modules, (8) 50 or 100 watt modules, or (4) 600W/1200W/1500W modules in a rack, as well as many combinations within a rack and the ability to parallel racks for added power.
multi-output 1U power rack for up to (4) 50, 100 or 150 watt modules, as well as many combinations within a rack and the ability to parallel racks for added power.
Front panel meter optional feature (600W/1200W/1500W Models only).
Parallel for N+1 redundancy.
Or-ing diodes built in.
Voltage trimming from front panel.
Remote voltage control of 600W/1200W/1500W modules via trimpot or voltage source.
Remote ON/OFF of 600W/1200W/1500W modules. (Available as an option for 100W-1UR and 150W-1UR models; contact factory for details.)
Individual current monitor optional feature. Voltage proportional to current allows monitoring individual current output of 600W/1200W/1500W multi-unit configuration. Contact factory for details.
Plug-in construction. Easy mount and dismount.
Keyed construction to prevent incorrect module placement. The HSF are keyed according to their voltage rating. When the corresponding rack adapter key (pin) is installed by a user, only an HSF of the correct voltage can be inserted into the keyed slot.
Built-in EMI filter attenuates the conducted noise below the requirements of both FCC and VDE 0871 for Class B computing devices.
Separate remote error sense terminals: (all except 1200W/1500W models) to compensate for voltage drop of connecting wires
Forced current share is used to configure an N+1 system. When the current share bus of paralleled HSF are connected together, the load current divides equally. If one unit fails, the remaining units will divide the load equally among themselves and continue to supply uninterrupted current to a critical load. The failed unit is isolated by built-in or-ing diodes.
Built-in alarm relay provides either normally open (close on failure) or normally closed (open on failure) contacts that may be used to provide an external failure indication. 600W/1200W/1500W modules also have a logic alarm signal (±PF) that performs the same function.
24 pin connector used to obtain mains power and provide output via corresponding mating connector in the rack adapter.
Reset Button (350W/600W/1200W/1500W units only) to restore the output if the unit shuts down after sensing an over- or undervoltage condition, thermal overload, or fan malfunction.
Safety: designed to meet UL 1950, CSA C22.2 No. 234 (M90) level 3 and EN 60950 (a-c input only).
CE Mark: Units are CE marked per the Low Voltage Directive (LVD),73/23/EEC and 93/68/EEC.
Bellcore Requirements: Designed to meet NEBS GR-63-CORE. Certification passed: RA 19-6B with six HSF 150W units tested per GR-63-CORE, Level 4 (Earthquake and office vibration). A video (MPG, file size 13.5M) of the NEBS GR-63-CORE earthquake and office vibration testing is available for viewing. A zip file (file size 12.1M) containing the MPG video can also be downloaded for off-line viewing.
The unit is supplied with a 5 Year Warranty.
